Parallel-flow slotted sieve tray efficiency

Air Distillation

“…One competitor used for example parallel flow slotted sieve trays [7] and another one slotted trays of the Kühni-tray type [8]. The internals of competitors may differ because they have developed different engineering solutions for the given task.…”

The Evaluation of Out-of-Level Trays for the Improvement of Industry Guidelines

“…A literature search was performed that not only included public domain materials but also reports/ papers internal to Koch-Glitsch (confidential papers are noted accordingly). Data from six public domain literature sources was used (2,3,4,5,20,21) as a basis for evaluating previous test data on trays set at an angle. Many more papers stated poor column performance with trays tilted, but provided no performance details; hence these references could not be used for any quantitative analysis.…”

Effect of Liquid Channeling on a 1.8-m Distillation Sieve Tray

“…Mass-transfer efficiencies were determined by stripping acetone from water using air. This is a convenient system to use since the slope of the equilibrium line is close to unity, and so the results are relevant to distillation systems (Lockett and Augustyniak, 1992).…”
